Looking at purchasing a 1991 26' Hi LO, Does anyone know what the A/C unit would have been charged with? (R12 or R22)

If in good condition what might it it be worth?? What items might be a good area to look for troubles before purchasing?

This was taken from NDgent's post here on the forum. It is a great go-by list. You can do a search of thinking about buying and find his post to read it first hand.

Basically, start with the visual items –
1. Exterior
• Look for water stains and discoloration on inside walls and around ceiling anywhere vents, skylights, windows, etc. exist.
• Push and prod with your hand on the inside walls for soft spots (which could indicate a water leak and a damaged or rotten interior wall).
• Check for bubbles in the wallpaper (a sign of delimitation or water intrusion)
2. Interior cleanliness of the unit-
• Look for water stains and discoloration on inside walls and around ceiling anywhere vents, skylights, windows, etc. exist.
• Push and prod with your hand on the inside walls for soft spots (which could indicate a water leak and a damaged or rotten interior wall).
• Check for bubbles in the wallpaper (a sign of delimitation or water intrusion)
3. Test appliance functions –
• lights
• fans
• refrigerator
• air conditioner
• heater
• water pump
• range hood
• stovetop
• oven (if equipped)
• microwave (if equipped)
• stereo (if equipped)
4. Lift System-
• Does the unit raise and lower properly
• Check the lift system for hydraulic leaks (puddle under the trailer)
• Check the lift cables to see if they are in good shape and not frayed
• Check the seal between the upper and lower body halves for tears or damage
5. fill the tanks to the top and check for leaks
6. Battery
7. Solar Panel (if equipped)

R22 for the a/c unit, is the compressor running or is it just the double shafted fan motor? The nata guide might be low, check out rvtraderonline and craigslist nationwide for something in the 91 year to get an idea. Condition is important,check for soft walls caused by water leaks and the bottom rail of the top section to make sure it's not boed or twisted. Your looking at a value of $5000.
